Wouldn't go spending £100 on one but may be able to get one second hand.
I know the 3s-ge lump is hard to improve upon but i'm just thinking each little thing helps.
I got things like deck spacer, magnecor leads and de-cat on my list, thinking this could be worth adding just for a little more edge.
Definately feeling a better throttle response since K&N filter, platinum plugs, manifold wrap, throttle body clean up and egr blanked. Now i want more
Brake wise i'm just planning ebc front pads to match the rears and some good quality grooved discs.
plus front and rear strut braces, then get my trd skirts and rear lip fitted and painted then have Mondo heat my seats and omg this list never ends
